The balanced design of the eccentric cartridge and main shaft assembly fitted with Heavy-Duty Roller Bearings, ensure constant alignment and deliver a smooth & frictionless gyromotion. The top end of the main shaft is held in a heavy-duty Spherical Spider Bearing that acts as fulcrum for gyro swing and transfers the rigorous crushing loads to the crusher body through the spider arms. A set of thrust bearings of bronze and steel with a specialized metallurgy supports the main shaft and takes the wear and tear of the vertical crushing loads. The whole shaft assembly is hydraulically supported with a high precision shaft positioning mechanism for CSS adjustment. Automatic tramp iron release is built into the hydraulic circuit protecting the machine from overloads. A highly reliable oil lubrication unit that forms part of the hydraulic power pack and a separate high pressure automated grease lubrication system for spider bearing with all built-in safety features provide a trouble free operation of the machine. A positive air pressure seal combined with a mechanical seal provides full protection to all internals against ingress of dust in severest dusty environments. The drive to the eccentric mechanism is through a heavily built counter shaft assembly and high precision spiral bevel gear and pinion for long term performance. The crushing chamber profiles are designed for uniform flow and optimum material interactions to produce a cubical shaped product. A positive lock-tight fitting of mantle and concave with a backing compound provides an effective cushion to the manganese against the crushing loads. The machine is built to meet varied crushing needs- fine, medium and coarse- of hard rocks and mineral ores. The compact, well balanced, sturdy design and simple-to-operate features make the 3000 RBC NAWACONE an ideal secondary and tertiary crusher suitable for stationary, skid-mounted, portable or mobile crushing in toughest quarries and mines.

THE WORLD'S BEST DESIGNED CONE CRUSHERModels: SRM500 & SRM400 Durable NAWACONE Crusher for Secondary, Tertiary and Quaternary Applications   Features Exceptional Strength and Durability Combination of Roller Bearings and Hydrostatic Thrust Bearings for High Loads Highest Mechanical Efficiency to the Tune of 97% and Less Power Consumption High Productivity and Superior Product Quality Wide Range of Application Flexibility Fastest and Easiest Wear Liner Change Easy to Operate and Low Maintenance Costs Effective Tramp Iron Relief System Perfect for Portable and Stationary Plants The "Duracone SRM" models have several innovative design, construction and operational features that are unique and adds to their unmatched superior performance in secondary, tertiary and quaternary crushing applications.   It is extemely user friendly. e.g. the top shell can be removed and reinstalled in 20 minutes or less, whenever a liner change, or other maintenance needs that call for top shell to be removed, is required. All major maintenance can be done from above the crusher, or from outside the crusher The combination of anti-friction roller bearings in the eccentric drive, and the hydrostatic thrust bearing under the head, allow very high loading, and at the same time very low power consumption when running empty, leaving a high percentage of motor power available for crushing. The SRM models are field-tested for crushing river gravel with a compression strength upto 70,000 psi The low friction in the drive also prevents the shaft spinning when the crusher is running empty, or is lightly fed with the segregated feed, and thus eliminates the need for a shaft brake The anti-friction roller bearings in the drive and eccentric mechanism ensure constant geometric alignment, which reduces wear and tear on the gear drive and thrust bearings compared to those fitted with bronze bushes It is perfectly well balanced, with the c'weights enclosed inside the eccentric mechanism, and thus the c'weights are not subject to wind resistance and abrasion The anti-friction bearing design for the drive and eccentric mechanism means crusher speed changes, if required to sent wider range of applications Low headroom for portable and stationary plants

It is sturdily built to withstand severe crushing loads generated by toughest of the rocks. The main body is made up of top and bottom shells of heavy cast steel sections, precision machined to receive the spider bearing, eccentric and counter-shaft assemblies. The crushing chamber comprising of non-choking curved mantle and concave of high manganese castings, is designed to nip larger lumps of primary crushed rocks. And higher crushing volumes are achieved with evenly distributed wear. The forged mainshaft of special steel is precision machined and fitted with a cast steel core on which the mantle is mounted. A positive dust seal arrangement effectively prevents ingress of dust from the crushing area into the eccentric bearing elements and bevel-pinion gear train. The high precision gyro elements comprising of cast steel eccentric, set of inner and outer journal bearings of special metallurgy are driven through a bevel gear-pinion and counter-shaft assembly running on antifriction bearings. The eccentric and mainshaft are supported at bottom end by hydraulic pressure through a set of thrust plates for taking the vertical loads. A hydro-lube system incorporates all machine-safe controls. The lube pump circulates and lubricates the gear train, main & counter shaft bearings. The hydraulic circuit ensures smooth CSS adjustment and trouble-free operation of the crusher. The spider bearing in the top shell is grease-lubricated either manually or by an automated grease pump (optional).
